Visitors to the village are usually offered a bowl of mazato as a sign of welcome.
I've drank many bowls of mazato with no ill effects save for an unpleasant headache the next morning.
I bartered for this ladle at a Urarina village along the Rio Chambira. The ladle is about 3 feet long and made from an interesting hardwood. It's stirred plenty of mazato and shows some use along the edges.
